SUMMARY:

  1. Simple interest:
  2. If the principal remains the same throughout the loan period, then the interest paid by the borrower is called Simple interest.
  3. S.I. = (P×R×T)/100
  4. Compound interest:
  5. If the borrower and the lender agree to fix up a certain interval of time so that the Amount =(Principle+ Interest) at the end of an interval becomes the principal for the next interval, then the total interest over all the intervals calculated in this way is called compound interest.
  6. Let P be the principle and the rate of interest be R% per annum. If the interest is compounded annually then the amount A and the compound interest C.I, at the end of n years.
  7. Given by A = P(1+R/100)n
  8. and C.I = A-P=P{(1+R/100)n-1} respectively.
